ABSTRACT

A distinct cultivar of Chrysanthemum plant named ‘Yogabriella’, characterized by its upright, mounded and rounded plant habit; freely branching habit; dense and full plants; uniform and freely flowering habit; daisy-type inflorescences; golden yellow-colored ray florets; bright yellow-colored disc florets; and natural season flowering in early October in the Northern Hemisphere.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Chrysanthemum×morifolium cultivar Yogabriella.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially known as a garden-type Chrysanthemum and hereinafter referred to by the name ‘Yogabriella’.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.

The new Chrysanthemum originated from a cross made in March, 1999, in Salinas, Calif., of a proprietary Chrysanthemum selection identified as code number 94-L254002, not patented, as the female, or seed, parent with a proprietary Chrysanthemum selection identified as code number 95-L262001, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Alva, Fla. in November, 2000. The selection of this plant was based on its desirable inflorescence form, attractive ray floret color and good garden performance.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Alva, Fla. since January, 2001, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yogabriella has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yogabriella’. These characteristics in combination distinguish ‘Yogabriella’ as a new and distinct cultivar:

1. Upright, mounded and rounded plant habit.

2. Freely branching habit; dense and full plants.

3. Uniform and freely flowering habit.

4. Daisy-type inflorescences.

5. Golden yellow-colored ray florets with bright yellow-colored disc florets.

6. Natural season flowering in early October in the Northern Hemisphere.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the female parent, the selection 94-L254002, in the following characteristics:

1. Plant habit of plants of the new Chrysanthemum was more uniform than plant habit of plants of the selection 94-L254002.

2. Plants of the new Chrysanthemum flowered more uniformly than plants of the selection 94-L254002.

3. Plants of the new Chrysanthemum had daisy-type inflorescences whereas plants of the selection 94-L254002 had decorative-type inflorescences.

4. Plants of the new Chrysanthemum and the selection 94-L254002 differed in ray floret color as plants of the selection 94-L254002 had purple-colored ray florets.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the male parent, the selection 95-L262001, in the following characteristics:

1. Plant habit of plants of the new Chrysanthemum was more uniform than plant habit of plants of the selection 95-L262001.

2. Plants of the new Chrysanthemum flowered more uniformly than plants of the selection 95-L262001.

3. Plants of the new Chrysanthemum had daisy-type inflorescences whereas plants of the selection 95-L262001 had decorative-type inflorescences.

4. Plants of the new Chrysanthemum and the selection 95-L262001 differed in ray floret color as plants of the selection 95-L262001 had red-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Bengal, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Bengal in the following characteristics:

1. Plants of the new Chrysanthemum were larger than plants of the cultivar Bengal.

2. Plants of the new Chrysanthemum had slightly larger inflorescences than plants of the cultivar Bengal.

3. Plants of the new Chrysanthemum had fewer ray florets per inflorescence than plants of the cultivar Bengal.

Plants of the new Chrysanthemum can also be compared to plants of the cultivar Sandy, disclosed in U.S. Plant Pat. No. 7,531. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Sandy in the following characteristics:

1. Plant habit of plants of the new Chrysanthemum was more uniform than plant habit of plants of the cultivar Sandy.

2. Plants of the new Chrysanthemum flowered more uniformly than plants of the cultivar Sandy.

3. Plants of the new Chrysanthemum had slightly smaller inflorescences than plants of the cultivar Sandy.

4. Ray florets of inflorescences of plants of the new Chrysanthemum were more orange than ray florets of inflorescences of plants of the cultivar Sandy.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in a fiberglass-covered greenhouse in Alva, Fla. under practices which approximate those generally used in commercial garden-type Chrysanthemum production. One cutting was directly stuck in a 15.25- cm container in November, 2001, and exposed to long day/short night conditions. Plants were pinched once about five weeks after sticking. About one week after the pinch, the photoinductive short day/long night treatments were started. During the production of the plants, day temperatures averaged about 27° C. and night temperatures averaged about 21° C. Measurements and numerical values represent averages for typical flowering plants.
